one person buys a home cash and puts another person on deed, when sold how are the proceeds divided by the laws in Florida

Dear Anonymous:     If the deed list you both, and does not set forth a percentage interest that you own (i.e.: 60/40) then he cannot sell the house without you signing off on the deed to a new owner, and you own the percentage indicated on the deed , or absent a percentage listed, you own 50%.     That  said, because your boyfriend contributed all of the funds to purchase the home, he can try to assert an equitable lien on the property so that he would get more of the closing proceeds.  This becomes a little more complicated and transcends this forum.  However, he cannot sell this home out fron you.  I would try and work out an agreement where you are paid 50% at the closing.  If he doesn't agree you might want to consult an attorney.   Best of luck, Cindy S.
