Hi Lucy,
At the end of the day, what has to be considered are the needs of the family and the needs of the individuals. In considering this, you also need to think about the future earnings potential for both you and your husband.
Right now, the 'family' needs a home. WIth an 11 year old child, the parent who is going to take the majority of the care of the child has to be housed as a priority.
From what you have said so far, it would seem that you will be the parent who will provide the majority of the childcare.
Accordingly, when considering an asset split, it is likely that you would be allocated more than he in the equity of the house.
There are a couple of options to consider. If buying him out outright would be possible, but difficult, what about a part cash, part equity arrangement? He gets an affordable lump sum and a charge is placed on the property in his favour until you can afford to pay him off or when the house is sold?.
I presume that you don't want to sell right now, to keep your son's home life stable. Maybe in a few years, if he goes through the higher education route, you might consider selling and downsizing to release equity?
It does sound like you are doing all the running, and he is sitting back and making demands.
Without knowing the relative income levels, house value, value of other assets & pensions etc , it is hard to say what might be a reasonable settlement in your case. Certainly the starting point is 50:50 after a long marriage, but as your dear husband is about to learn, it doesn't work like that where children are involved. \Their needs are paramount in any settlement.
Ny ballpark guess (and I stress GUESS) would be that you should be looking for a 60 - 70% share of the assets to allow you to provide for your son going forwards, assuming that the husband is sharing the care of your son.
He isn't going to like what he hears in
mediation. He is also digging himself a great big hole in terms of his future relationship with his son. It is a terrible shame because he probably doesn't realise it at the moment.
Have you or he been to any kind of counselling service?
As to fight or give in, take the moral high ground. You are caring for your son. He is contributing little of nothing. Why should it be that way?
Suggest he takes a trip into town and finds a family law firm that gives a free 30 min advice session. Let him assimilate what he will hear from the professional. You telling him anything is no good, as you will be perceived to be the devil incarnate. He needs to hear it independently.
Best of luck Lucy, it won't be easy, but the facts are the facts.
