Can Dad get full custody of baby?

[HeavyMetalMama]

In an argument today my fiancé said that if I left him he would take me to court and get full custody of our baby (when he’s born, I’m only 5 months pregnant). It’s his first baby and my second and I would just like to say that I would never stop a Dad seeing baby ever unless it was for it’s own wellbeing. He struggles with his anger but says I’m “mad” because I’ve got PTSD and OCD. I’m a fantastic mother by the way. I live in a rented house with my son and my fiancé has no place of his own but does have a steady job whereas I’m struggling with disability and 0 hour contracts.
Just wondering if anyone’s had similar?

That's an extremely horrible thing of him to say even in an argument. Is he controlling in other aspects of the relationship?

He's talking out of his arse re taking you to court. A multitude of factors are taken into consideration when deciding custody and it is never as black and white as he seems to think it is.

Though if I were you OP, I would honestly ask yourself if this is a man you truly want to be with. Threatening the mother of your unborn child like that is truly disgusting behaviour.

I wouldn't be putting him on the bc then if he turns even more arsey he can prove to a judge he is a capable df before any contact happens. .

I must admit it wasn’t the nicest thing to hear. He struggles with his anxiety and I try to help him but I have stress induced seizures and had just come round from one (through arguing) when he said this. His temper is terrible and I do everything I can for him but it doesn’t help. He’s very stressed with work. It all sounds awful but it was better before his job stress, or we wouldn’t have planned this baby. I’m scared to put him on the BC but obviously we’re both his parents so we have to.

He’s not hugely controlling but it does my head in when he tells me what to do “for my own good” because of my health (epilepsy, possible fibromyalgia and spine problems) though I tend to do it anyway. We argue a lot because his work stresses make him horrible. I left my son’s Dad because I won’t have arguing around my kids and he’s too controlling to leave. He was perfect but I suppose they all say that.

You don't have to at all. You aren't married and you can't put him on unless he's there.
It's a standard threat chucked out by men to scare their partners. Very few follow through. And judges would be reluctant to take a newborn away from it's mother, particularly if breast feeding without an extremely good reason.

Domestic abuse can start or escalate when you are pregnant or just had a baby.

His actions aren't indictive of a normal healthy relationship. Abuse doesn't have to be physical.

You argue alot even though it causes seizures. Not good at all. He needs to learn to manage his work stresses and not take it out on you. I suspect however it's just an excuse and really he's an arse.

Seek help OP.

You really don't have to put him on the birth certificate - it's completely up to you.
He could apply to have it put on at a later date but it's not automatic since you aren't married

Legally you absolutely CAN refuse to put him on the birth certificate. You can also call the baby “Twinkledust Starbright” if you want and there is nothing he can do about it. You are not married so his connection to the baby doesn’t start until either he gets a court order or you choose to put his name on the certificate.

Make sure you give the baby your surname. (Realistically you will be the main carer so much easier if you two have the same name.)

If you finished with him then I suspect your seizures (and so disability) will reduce massively as you said they are stress related and it is him that is causing you all the stress.
