I am soon to be married & I am looking at applying for joint home loans with my partner and purchasing a property before we get married. My partner will be paying a sizable deposit for the property and I will not, however we will both contribute to the repayments of the loan. Is it possible to get a legal agreement that states the amount of the deposit/money my partner put towards the loan and that if we were to divorce that money is rightfully hers and anything other than that specified amount is for both of us to share? Will this involve a costly prenup agreement or is this a simple legal agreement based solely on the deposit my partner will be contributing? Are you able to provide an approximate ballpark figure of what it would cost to prepare a basic financial agreement?
