A lot of people manage most of their divorce with only very minimal input from solicitors. This is possible because they have a reasonable and cooperating ex and they too are reasonable and cooperating. Divorces become complicated and expensive for many reasons. Top of the list is when either or both party form unachievable expectations of what they can do and what they can get.
Having an objective and informed understanding of what you can realistically achieve and how to go about it is vital whether you settle between yourselves or go to court. Lawyers can provide this expertise, experience and objectivity.
In your shoes I would work out what you can afford to spend on a divorce. This will then inform how you spend it. Disclosure and confirmation of assets is a really important element of a divorce. It doesn’t necessarily need a lawyer for you and your ex to get to this point. It usually needs a lawyer to assess what you are then entitled to based on your needs and his needs.
Your needs defined by a combination of your income (salary, benefits, child support etc) and outgoings. For the purposes of the divorce parties must maximise their income and minimise their outgoings. This is something you can draft without a lawyer. But a lawyer may need to look it over.
In your case your ex seems willing to move forward with a financial settlement. He is of course being self serving in wanting you to move to a rental or social housing. You want to own which is also self serving. But you are both getting way ahead of yourselves and arguing the toss.
You need to first identify and agree what your marital assets are and what your needs are. Then you or a lawyer will be able to see what you are entitled to.
Mn and other social media forums will be full of people screaming that you need a shit hot lawyer, a barrister and a forensic accountant. Well maybe if there is a huge asset pool. But if it is limited and you cannot afford it the divorce will be on a budget. You will have to use lawyers judiciously and a forensic accountant won’t be worth it.
If you are going to divorce then file for divorce. Ask him to pay half. He can only say yes or no. Then you can arrange mediation. He can only say yes or no. Mediation will involve disclosure and identifying needs.
At the end of the day in the Uk you need a huge income and/ or a huge deposit to buy. If you can’t improve your income and there isn’t enough marital assets a lawyer won’t change that.
