He needs to get proper legal advice. Spousal support is rare. Usually in cases of high earners where the other one has made career sacrifices to raise kids.
Its unlikely she will get any, but no one can say 100%. She may apply for it as a bargaining chip, to try and get more of the money that's in the bank. She may mo intention of wanting it.
But if her pension is shit, she may get an equivalent chunk of his. She may mor as she has had the opportunity to build her own.
He needs legal advice because she will keep trying to get more and more.
When divorcing dont believe if the other person says they have had legal advice and you have to give them xyz.
Bils wife told him that she solicitor told hee she would get spousal support. He earned 22k, no shared kids. Her kids were now all adults and it turned out for the last 5 years of their marriage she claimed they had split up and was claiming benefits as a single disabled person. Despite him working. He had no clue.
His solicitor pointed out that she had, in paper being supporting herself for 6 years. The solicitor suggested that any effort from her to suggest that wasnt the case would mean she was admitting to fraudulently claiming benefits. Also he didnt earn anywhere near enough to pay spousal support or have much of pensions. No house etc. Thw divorce wa dealt with quickly and she crawled back into her hole.
