My boyfriend and I purchased a house together. I put down 89% of the down payment. He put 11% down. We are now selling the house (we have only owned it for 4 months) We will be taking a loss on the house. There will probably only be $24,000 left after closing and we put $44,000 down. How should the $24,000 be split?

You should get 89% of the $24 K, of course.

However unless the two of you can agree, whatever escrow agent (title company frequeently) is handling the closing will not be able to disburse the proceeds and the matter would have to be settled in court.
