So sorry you are going through this OP.
I know things feel awful now,
However, truly there is hope.
, and there are actually plenty aspects to what you mention that are positive. It sounds like You are in a much better situation than many women when they go through this financially. You need to talk to a lawyer to answer your financial questions, but my non expert understanding, having gone through divorce in the uk is:
1.- he would most likely be entitled to half the equity in the house, but may not be allowed to access this until your child is an adult. Ie he has to leave the equity in the house. This is most likely true if he can support his own living situation without hardship, without selling the family home. If you are in an 800k house, and you hardly work, that would suggest he is a high earner and he may be expected to support himself without selling.
- After a long marriage, if you have been a stay at home mother, and he is a high earner, then he would normally be expected to pay spousal maintenance, at least for some time to help you transition back to work
- Your lawyer might be able to argue that your own property, as it has always been in your name, purchased before, and if never used by the two of you, is outside the marital assets. This would be messier if you didn't put any deposit into the family home, allowing you to maintain it etc,.. however, even if a marital asset, you could potentially use your half to buy him out of the family home, if needed.
- Assuming you are the residential parent, and he is not taking your son 50-50, he will also owe you child maintenance payments.
However all this is generic advice from an amateur. You need to first go online to reputable sources and check the laws in your region. Get smart and empowered. You then need to make a short list of questions you can't find the answer to/need to confirm, and make an appointment with a lawyer. If you do this, ask for their questionnaire in advance to fill out all the basic information. This will save time and cost. And be very factual and directive. Minutes cost, and telling them how awful you feel and why you think it didn't work out is generally irrelevant and expensive!
With your son, truly he will be fine. My daughter was six at the time, and she was a bit disrupted for a while, but is happy, well adjusted, and has a way better life than she would have enduring a shit parental relationship,
The best thing you can do for your son is be healthy yourself. Take care of course of, feel your feelings, give yourself compassion, pick yourself up and champion yourself and your son through the settlement process.....
I'm sending you hugs. Xxxxx
