Relationship over, ex keeping ‘joint savings’

I was coming to say this. You need to pose a threat to his job if he's in finance as he will care about that

Op would be foolish to wait for any action from the police. That won't get her any money back and even if it did, criminal trials are taking at least 18 months. She needs to act now. Equity actions should not be delayed.

Just to add - although the small claims track is normally limited to £10000, this is such a straightforward matter you can ask for it to be allocated to the small claims track rather than fast track. That is very helpful to you because if he engaged a lawyer to appear (he'd be an idiot but sounds an idiot anyway so he may be) for him you will not be liable for any costs.

This is fraud.

He told you he was saving in an interest bearing account and then invested your funds in a volatile asset class in an ISA - in his name only.

I suspect he has lost a chunk of your money. That is his problem

I would tell him to either return you your 15k on you are reporting him to the police.

The CPS may decide to take no action as the burden of proof for criminal fraud is high

However once they have said “No” you can then begin a civil claim against him.

The burden of proof is lower

The case will need to be heard before a judge and it is really risky for him to lie in court as if found out it is potentially career limiting.

Once this dawns upon him it might prompt him to return your money.

Also talk to you local Citizens Advice as most of the people posting here are clueless

Op some of the advice on here is batshit.

You should add up the exact amount of the transfers you have made and when. Write him a letter before action along the lines of 'On the dates as listed below, I transferred the amounts as listed below into your account. The purpose of the transfers were for us both to save up for a house deposit because it was our intention to purchase a house together.

On xx date our relationship ended.

On x date you informed me you had placed my money into your isa account.

I have asked you verbally on x date and x date to return my portion of the money. You have refused.

This letter is to inform you that if the sum of £xxxx is not returned to me into account number, sort code, name on account, within 28 days of the receipt of this letter, it is my intention to ask that the court issue a claim against you.

I shall ask for the costs to be awarded against you, and that statutory interest @8% be included from the date of receipt of this letter.

I shall also ask the court that you account for my share of the interest up to the date of this letter.

Yours sincerely

That should do it.

If you don't receive the money, go onto hmcourts money claim online and issue the claim. You have a very strong case against him. Any questions?

Although here it says must subscribe (pay) with their own cash (as is tax free) so if op can prove it is her ££ maybe maybe .

If your dad is able to help you sort this out then get him onto it ASAP. The more people who know what your ex has been up to with your money, the better.

He absolutely can return your money.

If you have proof of the fact you gave him money to put in an interest bearing account as joint savings and you presumably have proof you transferred the money each month, then I would calculate what the total should be if he had done as he said and issue a letter before action demanding that money back within, say, 2 weeks.

What he has actually done with the money seems irrelevant to me, he owes you your money back with interest and you need to move forward in using the law to reclaim it.

Would he be keen to find out?

Some investment platforms (Chip for example) use levels of 1-7 to illustrate how risky a product is. 7 is the highest risk so potential for big returns or big losses. It's irrelevant to this really, he might incur a penalty but can get your money back & he should have thought about that before risking your deposit in a high risk account without your consent.

I agree with the PP who suggested he may have lost & is bluffing in the hope it will recover. Fuck that - he can give you your 15k and take the loss on his crap investment.

Tell your Dad. If he's usually supportive, he will want to help you manage this, you don't have to worry on your own.
We all make mistakes & we all learn from them

I’m not convinced it’s a crime.
no written agreement between him & OP.

This explains stocks risk level for isa https://www.aviva.co.uk/retirement/fund-centre/investment-funds/risk-ratings/#:~:text=Risk%20and%20return%20are%20linked,the%20long%20term%20is%20higher.

Exactly. It goes with the markets. Ours lost about 10% when Trump was playing silly buggers with tariffs but they’ve gone up a lot in the last few weeks.

How is it theft? She gave him money willingly

How is it fraud? Maybe if she can show he defrauded her. ??
Op can ask for "her" money back.
He can say what money? It is my account.

If there is interest it may be getting reinvested

This.....

This. I have one of these accounts and you can cash it in at any time. Do you have records of what you transferred to him?

You need proper financial and legal advice.

Hmm just because of this doesn’t make him expert unfortunately even though he might think he is …

Because he works in finance for a bank. What he's done may potentially be fraud and theft.

level 7 Sounds high risk OP 😬
I am hopeful this will get sorted amicably between the two of you

He can sell the units for the value of what you’re owed, it’s a slightly longer process as he’ll have to contact the management company and complete the administration before they’ll release “proceeds”
