Hi and thanks for the posts we have been married 27 years so you said deposit i put down on new property is joint [ie profit from joint property] so he is going to spend his profit holidays and i want to put towards a new property so he can have his holidays and still claim on the deposit [profit ] i put down on a new property ? CONFUSED
You need to get a Consent Order signed and approved by the court that details your agreement to share the profit from the house.
Then what he does with his share (e.g fritters it away) is his business. You share is safe.
If however you just split the profits by verbal/informal agreement without a Consent Order then you do face the risk that he could waste his share and then come back to claim some of your assets at a later date.
