To OP
No two Divorces will ever be the same so listening to generalizations can be dangerous. I am not a family solicitor, but my understanding is that the Law applies equally to both genders.
Asset split will be based on many factors such as; length of marriage, age of children, earning potential, pensions. On the assumption that you will be the main carer the fact that there is a 6 year old child and you have historically earned much less is in your favour. However, Courts will also take into account that your ex has needs too. He needs to have; a roof over his head, food to eat, clothes to wear, etc.
Courts are unlikely to plunge one partner into poverty so the other can continue with same life as beforehand as though nothing had happened. If there are insufficient assets to go around (often the case) then both partners will have to accept a reduction in standard of living which will of course affect children too.
If you both complete Form E accurately and truthfully experienced family solicitors should be able to make a deal that is fair to both. However, if Courts become involved costs can rise rapidly which serves only to deplete assets.
Suggest you concentrate what is best for the 6 year old child rather get into a contest with ex over who gets what.
If you are the main carer then Child Benefit should go to your account. You will be able to claim Child Tax Credits too even if not working. If you work part then you may qualify for Working Tax Credits and possibly help with childcare. Make sure you claim the Council Tax reduction for being the only adult in the house.
Child Maintenance your ex should pay can be obtained from the online calculator. Look at the link:
www.gov.uk/calculate-your-child-maintenance
Divide your ex yearly earnings by 365 and then multiply by 7 to get the weekly amount. Enter this into the calculator and then enter the number of nights, if any, the child will stay with their father.
Suggest you do this via CMS. Application costs 20 pounds, but worth it as once they have made an assessment it is binding and can be back dated to the date of your application.
Tricks to watch out for that your ex may try to reduce Child Maintenance are; asking for 50:50 shared care of child. This results in fathers paying no child maintenance. Fair enough if both parents earn the same, but if there is a large difference it is wrong in my view. However, that is the current legislation.
Changing addresses and employers is another way of trying to evade CMS. Working on a self employed or through a Ltd Company seems to cause trouble too.
As for your Solicitor advising that you need to look for work I would say they are correct. Courts expect single mothers to work part time once children reach age 7 and move to full time once children are older.
Spousal Maintenance has no standard formula and can only be awarded by Court Order. Even if awarded it may only be for a short time as other poster has already said.
Good luck.
