How much do I owe ex?

My partner of seven years ended our relationship today. We weren’t married and have no children together, but he has been an excellent step-parent to my three kids and I am heartbroken. When we met, he had been made redundant and as a result had 5 figure debts. Over the years, he since built a successful career, paid off his debts, and gained a degree, while I also progressed in my career and completed a master’s degree. He also inherited £20k, which he spent on a holiday—none of it came my way.

We are now struggling to reach a fair financial separation. He moved into my home in 2021, at which point I had already paid off nearly half of my mortgage. Initially, he paid £425 a month (which included bills), this later increased to £600 in 2022. About 20 months ago, when my mortgage was half paid off, he took over the £1k monthly mortgage payments and continued to pay around £400 towards bills. I paid for the big grocery shops.

Now, he’s asking for this £20k back, saying that’s what he has contributed to the mortgage. We never had a legal agreement in place, as neither of us wanted to spend money on lawyers. I want to do the morally right thing.

what do I owe him? I will have to sell up either way.

Zero

AnyUmbrellasToFixToday · 30/03/2025 20:27

Honestly, if you had no agreement, you owe nothing. But he could litigate and a judge would then decide what was 'fair'. He can't give back the food he ate, but you could deduct the value of it from his 20k, and that's probably a figure a judge would start at.

2025willbemytime · 30/03/2025 20:29

Why do you think you owe him anything? The money he thinks he's paid off your mortgage is actually rent for living in your house. Funny how he spent 20k on a holiday and he's saying that you owe him that much.

socialworking · 30/03/2025 20:29

At the moment nothing, but as the PP said he could take you to court and claim part of your property. If successful he could potentially have a charge applied. I’m not sure if he could force the sale over that amount but I guess it’s possible.

Nosaucelikemintsauce · 30/03/2025 20:39

Nil.
Zilch.
Zero.
Don't be bullied into paying him a penny...

Dumpedonmotheraday · 30/03/2025 20:41

Those of you saying zero. On what basis?

In the basis that if he wasn’t living with you he would be paying full market rent somewhere else.

dirtyyoungtown · 30/03/2025 20:43

You owe him absolutely nothing. Tell him to take you to court and a judge would tell him the same thing.

Unless his name is on the mortgage he has no entitlement to any payment. He was essentially paying rent to you to live in your house.

MagicPharmacist · 30/03/2025 20:44

He was paying rent to you to live in the property that you solely own. He doesn’t have an automatic claim on your house.

He could take you to court and make a claim but he’d have no guarantee of being successful and the cost of court would v likely swallow up any money he’d claim even if he was successful.

Dumpedonmotheraday · 30/03/2025 20:44

He wouldn’t take me to court. I know this for sure. I just want to do the right thing.

He's pushing his luck.

Do not give him a penny.

He lived very cheaply until 20 months ago. Calculate the going rent and back charge the greedy sod.

Washingupdone · 30/03/2025 20:46

Contact citizens advice bureau or a solicitor as soon as you can so you don’t have to listen to what he wants.
Good Luck Flowers

Catastrophejane · 30/03/2025 20:47

you owe him nothing. It’s your home and the money was basically rent. Particularly as you were paying other bills ( which probably adds up to the same contribution as the mortgage)

BaronessEllarawrosaurus · 30/03/2025 20:47

How much has your house increased in equity over the 20 months he took over the mortgage. He will be entitled to some but I doubt it's anything like the 20k he's asking for

Cerialkiller · 30/03/2025 20:48

Agree with pp let him take you to court. If he actually goes through with it then I might offer him something (e.g.5k) to settle rather then do to court but otherwise I would self represent and see what the judge had to say.

I would trawl through your bank statements for the last two years and work out exactly what you spend on household food in that time, make sure you include any other major costs you covered. Food costs have risen a lot so i wouldnt be surprise if half your food bill is a big chunk of the money you 'owe' him.

Did you support him at all while he was in debt? Did you cover his bills or not charge him rent for a period so he could service the debt?

The right thing is for him to thank you for supporting him while he cleared off his debts and studied. I’m guessing he was paying next to nothing in that time?

KarCat · 30/03/2025 20:48

What a dick.
You owe him absolutely nothing
Dont let him bully you!
if necessary consult a solicitor, to put your mind at rest, but legally he’s intitled to fuck all
Thank God you didn’t marry him!
Sending love x

Goody2ShoesAndTheFilthyBeast · 30/03/2025 20:49

This 20k, is that everything he has paid for bills and expenses since he's lived in your house?
Does he think he gets to live for free then?

MissMoneyFairy · 30/03/2025 20:49

Why does he think he can have 20k back, does he expect to have lived rent free for 20 months.

TY78910 · 30/03/2025 20:50

I would calculate a fair monthly rate for rent based on similar sized rooms in your area and calculate over the last 4 years. Then you can perhaps return the difference, if you want to be nice.

MinnieCoops · 30/03/2025 20:51

Nothing except a robust see ya later

CarrieOnComplaining · 30/03/2025 20:51

I would pay half the mortgage payment he took over 20m ago so that you contributed to the roof over your heads equally during that time.

So £10k.

If feeling generous.

Maybe deduct some for his share of big grocery shops.

The early money he paid you was a contribution to a roof over his head. Life would have been a lot more expensive for him had he had to rent a place and pay bills.

But, he has made no complaint, asked for no contract all these years, if he wants out now, fine, but he seems to have no right to take your money with him.

cestlavielife · 30/03/2025 20:52

Nothing
He was a lodger paying rent

Catastrophejane · 30/03/2025 20:52

Also,OP…

you say he wants 20k from the mortgage? But you
wouldn’t get that back. Most of that figure is interest - it’s probably only a couple of thousand off capital sum.

but it’s all academic anyway. You owe him nothing.

The right thing is to look after your kids, he's paid rent and has paid off his debts. You owe him nothing, tell him to move out tomorrow 💐
