Please help my SIL regarding getting what is rightfully theirs

[ELF1981]

• SIL brought a house with her boyfriend, been in the property for over a year.
• He told her he wanted the "single life"
• She moved out to give him "space"
• Three months down the line, they are split up
• She is living at her dads
• He is living in the house
• House on the market She has stopped* paying towards their mortgage - he said he was happy with this and they would adjust the profit on the sale to account for the amount he has knocked off.
• She went to the house to get a DVD player (there is two) some pictures (to split) - he was in the house and she arrange to go up there.
• He has since told her that she is not allowed to take a DVD player, she is not allowed to take any DVD's, nor the second telly. He has told her that HE owns these (he was a higher earner, some items were hers before they moved in etc)
• He has said she is allowed the bed (?!) and some pots and pans and he is keeping everything else - spare bed, sofas, TV's, TV units, DVD's, kitchen appliances etc.
• Where does she stand?

if her name is on the mortgage/deeds tell her to move back in - she can then agree to move out again when she is happy with the possessions she is "allowed" to take. Sounds like this may be the only way to protect her interests.

I have told her to move back in, when she says she is (in the spare room) he says he is going to move into his Grans.

I like them both and dont want to get stuck in the middle, but obv want to ensure she gets what is owed to her!

Is the house on the market for more than they brought it for? With what is currently happening in the housing market, she might be better to walk away and avoid having to stump up for a bit of negative equity.

They are looking to get £7k profit each from the house - it is on for a lot more than they bought for - but he can obviously hold the sale up as long as he likes.

They can both hold the sale up as long as they like.

She is entitled to take anything she wants - she does not have to ask permission.

She should also still be paying her half of the mortgage (this keeps things simple if god forbid this turns into a long protracted argument)

I would also move back in If I were her (if she can stomache it) - if he moves out, rent out spare room to cover the mortgage he may or may not pay.

checkout this and this

basically if not married any assets "belong" to the person who paid for them.
