advice with financial settlement

edgarjay

i am after a little advice or opinion if possible pls, but quite long winded so here goes:
i split from my wife in July (mutual split no blame) and she started divorce proceedings which are now almost complete, she has applied for the decree absolut but we have to go to court on 28th feb to sort the financials and this is the problem!!
basically when we got together ex was a student and i owned my own house, which i sold 6 months later cleared any debts and the remainder paid for the deposit of our house together, when we bought the house ex was not working for a solid 10 months so i paid the mortgage etc from my wages, ex then took a temp job for 6months and discovered she was pregnant, she left this job in Sept 2005, and as she had not paid enough nat. ins could claim £0, so again we coped on my wages until the baby was born in March 06, when she received SMp of around £100 week, we had run up quite a few debts by this time and ex went back to work in June so we decided to re-mortgage and take a secured loan to pay off debts etc. i had an endowment policy which matured in Aug 06 (£3000) which i used as a deposit to pay for ex a nearly new car and rest on finance

however when we seperated ex insisted that these were my debts and she wanted to keep house and car, i stupidly agreed to take a personal loan for £15,000 to clear secured debt (£12,000) and car (£2,100) and sign over everything to her in exchange for joint custody of our daughter and no maintenance payments until this loan was cleared (5 years).
thats the house and all contents & car, however we still had outstanding payments on a new suite £600 which i paid and was still paying the mortgage until Aug 07, when i decided i could only afford half mortgage which she agreed to as long as i paid off the suite.

ok so this is my quandary, i have signed all the papers, can i now change my mind when we go before court?
my feeling is that i have equity in this house of around £12,500 (now worth £25,000 more than we paid) that i would like to go to my daughter in the following circumstances
1. ex moves someone else into house: she pays the 12,500 into a trust fund at a rate determined by her as long as it is there by time daughter is 19
2. ex sells house: the 12,500 goes straight into a trust fund until daughter 19

remeber in 10 years the house could sell for £10,000 more than worth now, but i dont wanna claim any future equity just whats there now
i do not want any cash or other assets from house just want to know that what little i have from the marriage is secure for my daughter, ex is only 22 and plenty time for her to have more children etc. that would obviously then benefit from any equity that should belong to daughter, i am 35 so not much chance for me having more kids (lol).

sorry for long post but if you taken time to read thanks and any advice welcome xj
