My Partner and I have been together five years, his ex left him and also left him with their two children 6 years ago they were 8 and 6. She is an alcoholic and since leaving has not contributed any child support financially. She has been very in and out but over the last year has done a lot better. She asked him for a divorce a couple of years ago but he felt that she wasn't mentally stable and did not want to file and end up pushing her mentally so ignored her request. Now she is doing better he filed for divorce after five years, thinking she would sign and send papers back. Instead she is asking for financial disclosure and saying she is entitled to something as they were married ten years, but they were married for five. During the marriage she drank very heavily, lost a business, they lost a house and then moved into social housing. When she left, she says she left with nothing, but she moved into a rented flat and the first months rent, deposit and estate agent fees were paid from their joint account, this was £1680 for rent and deposit and £675 for estate agent fees. My partner also agreed that the family allowance still be paid to her so she had a bit extra for when she saw the children. This had to stop when it was found out that she was claiming that the children were living with her and was caught committing benefit fraud.This meant that her rent was being paid as she had misled the benefits and claimed the children were living with her, she did this by going behind my partners back and changing the address for the children at the doctors so she could prove to the benefits people that they resided with her, it was all very underhand. When she left all that they owned was £4000 in ISA and my partner has a pension that even when he retires is only worth £28,000. Also when they lost the house during their marriage they had to borrow money from her parents of £20,000 and since separating my partner has paid his half back to them and she has not. He is a decent man and has never put pressure on her to contribute as he knows she has struggled and does not have a job and is on benefits. Can someone please tell me how much she would be entitled to? They own no property together, she has paid nothing in respect of financially supporting her children and I just wonder if realistically she can take money from him even though our accounts are now joint and it has nothing to do with her. Literally all he has is pensions and some money in savings less than £5000 which is joint savings with me. Would this mean she can have some or would anyone looking at this say she has not paid child maintenance so she isn't entitled? I just struggle with the fact that she has contributed nothing to the children in the last five years, not bought anything as we provide it and then says she is entitled to money? The children see her and we are all amicable but this is baffling me. I legitimately just want to know what we might have to pay out. it is worrying me
