SIL had an affair and run off with the kids

BackoffSusan · 18/12/2024 20:59

Earlier this year SIL started behaving rather recklessly - lots of drinking at home, disappearing for over night benders with my brothers best mate, saying she wanted to stay in a hotel on her own and she hated being "just a mum". She'd only been married 6 months but I thought she was having a breakdown or depressive episode. She then instigated a separation from my brother in April. They both went their separate ways, and then in June it transpired she was in a relationship with my brothers best mate and been having an affair. The best mate then moved away in September - about an hour and half away from the town where she and my brother lived. Then last month she disappeared with the kids. Up to this point my brother had been seeing the kids twice a week with an overnight stay on the weekend.
My brother has no idea where she is. We assume she has moved in with the new bloke but she and new bloke have blocked everyone so we can't contact any of them. Brother has submitted all the paperwork for a child arrangement order but has been told it can take a really long time. I tried messaging her and ringing but she didn't reply, and then blocked me. I only asked if I could send the kids their Christmas presents or see them. I don't really know what else I can do. Social services and police have been very unhelpful. It feels like they just signpost to each other and now she has left the local area it's hard to know what to do.

Again, totally incorrect. Jesus I hope you’re not actually a cop. If you are you must have about 5 minutes service and need to get more training pronto.

Yes you're right it was a 5am answer, I have corrected myself. I meant that only the partner will be given the information disclosed. I'm not police, I never claimed to be.

In case you missed it op, the suggestion was to put in a freedom of information request to the school to discover which school she has enrolled the children in.

I wouldn't be so sure that the school know the name & address of the new school
There is a case in Ireland at the moment of a missing boy
His school were told he was moving across the border to a school in Northern Ireland (approx 30 mins from where he lived in roi)
No follow up was done by the school to ensure that he had started there. He remains missing and it doesn't look like there are any repercussions for the school so far.

Simonjt · 19/12/2024 06:52

This happened to a colleague, he reported his children and ex as missing to the police, he applied to the courts and hired a private investigator. It only took three weeks for them to be found, mum had moved in her new sex offender boyfriend and thought she would get away with it. As he had previous convictions my colleagues children were home with him very quickly as their mum wanted to continue living with her new sex offending boyfriend.

If the school are ignoring his PR he can formally ask for all information relating to his child, this will include any information regarding a new school as they will have sent a CTF over and recorded the name of the nee school on their MIS.

I know this is a hard question to answer, and there is no pressure to answer it here.

Is there any chance that he has done anything which has made her think that he might be violent or abusive? Or anything which could be constructed like that? Even at the end of their relationship when it was bad?

Her actions make much more consistent sense when viewed in those terms. Could she have left because she is scared of him and protecting the children.

@NC10125
We need to snap out of this frame of thinking, that women are always the victim of abuse. Lots of harm is being done to children because society can't accept that women can be just as selfish and abusive as men. Women are not always the victim & each case should be judged individually.

The kids in this op are being damaged by their mum's sexual desires & obsession with a new bloke. She was cheating on her dh, no sign of abuse; just an obsession with shagging her new fella.

Enterthedragonqueen · 19/12/2024 07:10

I would report the kids as being kidnapped by the best friend, this might get things moving a bit faster. Potential child abuser targeting a woman with suspected MH issues & vulnerabilities. This is what I'd suggest your db do.

EliflurtleAndTheInfiniteMadness · 19/12/2024 07:12

The assumption seems to be the mum's taken off with them so they're OK, but how does anyone know that? How does anyone know she's OK herself? Everything else aside shouldn't someone check that the children are well and ok, that they're alive, that they're enrolled in school, that they haven't fallen through the cracks. The thought that a woman and 2 little kids can disappear like this and all the authorities just assume everything's OK without even checking is scary. Not telling the dad, understandable. Just assuming they're fine because their mum took them not ok at all.

Owly11 · 19/12/2024 07:19

This sounds very distressing. This is a difficult question but is there any chance at all that your brother might have treated her badly? Usually when a woman disappears with her children without giving a forwarding address it is to escape an abusive man. I know you will be loyal to your brother but if he is the one feeding you all the information about her it might be worth checking out other sources of information about her too just to double check. If you are absolutely sure that this is not the case then can you think of any other reason why she might have done this? I hope you manage to get some info soon it sounds very upsetting for everyone involved.

KittenOnTheTable · 19/12/2024 07:28

He can also petition the courts to get the council to release school information. That's what my ex did. Even with the non molestation order in place he got it granted and he found out their school. So I wouldn't count on abuse being a factor either.
In scotland if it makes a difference

Justgoodforthegetting · 19/12/2024 06:15

I know, as a police officer of many years, that the threshold to take a missing person report is for someone to report someone else missing and have no clue as to their whereabouts.
It may surprise you to know that missing person reports are filed for teenagers that have stayed out past curfew, for men that have went on work nights out and stayed out all night without telling wife where they are, the threshold is surprisingly low, the only things we need to have are a person reporting that as far as they are concerned, another person is missing, and us not being able to immediately clarify that they are not.

As an adult, I could send my parents a text message and say I’ve decided to move elsewhere and want no further contact and I’d bet much be classed as a missing person if they decided to report me as one to police.

I don’t know, and neither does anyone in this thread, exactly what OPs brother has told police regarding the circumstances, I do know that some cops will do anything to avoid a bit of hard work if a loophole allows but “we” would very much be obligated to class her and the kids as missing.
After all, we can’t actually say for certain that she, or particularly the kids, haven’t come to harm, this needs to be followed up. Because if it isn’t, we risk a horrendous situation where mother and/or kids could potentially have come to harm and nobody would ever know. That’s why a cop needs to lay eyes on them all to confirm welfare.

incidentally, depending on how the circumstances were described to officers when OPs brother contacted them, it’s not a huge surprise that it was brushed off, what he needs to do OP is to say that ex and kids have disappeared into thin air, no clue as to their whereabouts, no forwarding address or school details, he has huge concerns over their welfare/wellbeing.

Im another one saying you’re wrong on this. They’re not missing, they’re with their mum. Police would not be obliged to class them as missing people. It’s a family court matter. It’s not laziness on behalf of police, it’s about not being overly intrusive in family life.

There will be a huge background to this that even the OP may not be aware of. I would absolutely not be surprised to find that there was allegations of DA in the background.

Marshatessa · 18/12/2024 22:18

I would report the children as missing to the police. This is out of character and not planned. They will then need to complete enquiries and a welfare visit to establish the children are safe.

Even if you do this and police locate them they won't tell OP's brother where they are.
The only way to progress this is through family court.

AVeryCovidChristmas · 19/12/2024 07:49

Freedom of Information requests do not work like this. They do not give information that breaches GDPR. The Police/SS can do checks if they believe there is a welfare concern. But they won't give your brother information on the DCs whereabouts, only let your brother know the DC are safe, and they will only check if they believe the DC are at risk. The correct procedure is to go through the court, who will trace the mother and then they can go through family court. Your brothers solicitor will have advised him of this. He needs to follow the procedure. I know it seems worrying to you OP but like you say, you don't know much of what has happened. Leave it to your brother.

BackoffSusan · 18/12/2024 21:16

@Sassybooklover he has seen a solicitor and filed all the paperwork for the child arrangement order but they have just said that all he can do is wait and that at some point he will get to see his kids again. But it might take a while. He has 50/50 parental responsibility so he has a right to see them.
He doesn't know ex best friends family or at least a way of contacting them and the ex best friend didn't really have any other friends. He was a bit of a loner. It all came as a bit of a shock because 2 weeks before she disappeared she was asking to increase the number of visits my brother had with the kids as she was wanting to spend more time with the boyfriend (overnight trips etc). The kids are 4 and 8. I don't really know what else to do. I don't think there is anything. I also wonder what the kids are thinking. I'd hate for them to think we abandoned them. They were used to regularly seeing their grandma (my mum) too so they've essentially lost a chunk of the family. SIL wasn't working either so I can't contact her through work.

Can anyone check to see if they are re registered at a nee school?
Also if you end up having an inkling of an idea of areas . Call around the schools and ask if ——- are present today ?
Your brother has the right to know if they are .

The school cant tell him the address but they can confirm if the kids are there.
Although this is maybe something better done after the Xmas holidays .

bigkidatheart · 19/12/2024 08:13

Do you know roughly where they have moved to? You said about an hour and a half away, do you know the town/city. Could you check electoral roll?

Does she not have any family you can contact? Did she have a local? Does she have a previous landlord, could you get a forwarding address from them? Does he have access to any bank accounts, hers or the children? There are multiple ways to find someone. Can you get someone she doesn't know to try and contact her, someone she would not have blocked, to let her know that if she doesn't make contact immediately to let you know the children are OK the police and social services are going to be involved?

He needs to go back to the police with his video evidence and report the children missing with a vulnerable parent (MH & drinking).

Survivingnotthriving24 · 19/12/2024 08:48

I think I'd be visiting all the schools in the area the new bloke lives at drop off/pick up in the hope of seeing what school the kids are at.

Report the DV and evidence to the police, having found out where the kids are to collect them with permission of the police.

thepariscrimefiles · 19/12/2024 08:53

InkHeart2024 · 18/12/2024 22:17

What exactly do you think 'authorities' should be doing? They are with their mum. She's clearly acted badly but expecting authorities to step in is bizarre.

OP just wants the authorities to do a welfare check and report back that the kids are OK.

The most dangerous person in a child's life is a new step-dad, and as these children have just disappeared from their dad's life, it is reasonable for him to want that reassurance.

BackoffSusan · 18/12/2024 23:42

@NC10125 not that I'm aware of but I don't live nearby so I don't see them regularly. I'd be very surprised, but I suppose it's possible in the sense anything is possible. It's true maybe I'm only hearing one side of the story. I never sensed any tension between them or witnessed any arguments. Neither of them had ever mentioned any disagreements. They have been together for 15 years and only married last year. At the wedding they seemed like a really happy couple, genuinely in love, a lovely family.
The only thing that sticks out in my mind - my brother said that when she started drinking earlier this year she would come home drunk and be abusive, as if she hated him - there wasnt anyyhing he could do to make her happy. He didn't tell me at the time because he didn't want anyone to know and thought she was depressed. It sounds very out of character and not the SIL I knew. But he's since shown me videos (after she instigated the separation) he had taken of her physically attacking him, and being verbally abusive - calling him ugly and old etc. To be honest I just thought it was because she was having an affair and wanted to leave him and was frustrated about it and her drinking exacerbated the situation.

I don't really see how she could think he had done something recently to make her think he was violent or abusive because he hadn't seen her since April apart from handover/drop off with the kids and nothing untoward had happened on those occasions. He had recently told her he was seeing someone about a month before she left. He was trying to move on with his life. She had asked to increase the amount of time/contact he had with the kids and they had been doing so.

I do think she is besotted with the new bloke. Before she cut her friends off they had raised some concerns that she was appearing to be completely enthralled by him, head over heels and in their opinion he was taking priority over the kids. So I think she was prepared to do whatever necessary to make a life with him, but this does feel drastic.

As your SIL's new partner was your brother's best mate, he must know his family quite well. Could he contact them for information?

Stillherestillpraying · 19/12/2024 09:02

I hope he has cut off any access to money that they previously shared. Smoke the nasty piece of work out.
And iI hope he gets main custody as she is clearly thinking more about her sex life than her children

I know OP wants this. But this would be an inappropriate intrusion into private family life unless there is actual reason to think they are at risk of harm. I am aware of stats around step fathers and abuse, but just the fact that they are now living with an unrelated man isn't evidence of harm.

People who want police and social services to have the kind of powers called for here would be furious if someone sent the police round to check on them on the off chance that something bad might be happening.

AVeryCovidChristmas · 19/12/2024 09:11

I can't believe some posters on here 'stalk schools' 'stop providing for the children, starve them out'. Clearly all a man needs to say is 'my ex was crazy' to bring out the worst in some women. Go through the proper channels, continue to provide for the DC.

Buttercup198 · 19/12/2024 09:16

Try the nspcc although without a address that will be prob impossible keep reporting to the police regardless they will eventually go around their

deeahgwitch · 19/12/2024 09:19

Is the new bloke your brother's best friend @BackoffSusan ?
How come if he is your brother's best friend he knows so little about his family ?
How long were there friends for ?

If I disappeared with my children and their father, my friends and everyone didn’t know where I was then I’d absolutely want the police to check on them.

I say this regularly though on threads where people are furious about school/police/social services intervention - if people want something done in a horrific cases then we need to accept occasionally something might be done to us if our kids say something worrying or they vanish.

They shouldn’t tell the OPs brother exactly where they are, in case they are fleeing him for good reason, but they should set eyes on the children.

And that’s exactly what happened when SIL’s ex disappeared with their children. And on a previous thread on here when the OP’s ex took her children. The slow court process was needed to get them back, but a check was done when they were taken without warning.

Surely, if you move in with a new partner and move with your children to an unknown location without informing the child's other parent, you wouldn't be surprised if the police came to your home to do a welfare check.

It would be unrealistic to assume that the other parent wouldn't try and find you and would just accept the loss of their children.

ExitPersuedByAMemory · 19/12/2024 09:32

This might seem like an unpopular opinion, but I do think social services should have been involved depending on how reckless the behaviour was. If SIL’s breakdown impacted the children, she could have received mental health support and there might have been some sort of family counseling or talking therapy being offered. She might be in a vulnerable position where she is now isolated from everyone she knows. And this might not be out of choice but to appease this other man, who I am assuming is OP’s brother’s “best” friend.
