EmmaHulbert - the whole ludicrous, disastrous system in England and Wales with regard to house sales/purchase. All ages, at any times.
Legislation is required to change the law - they say that moving is one of the top three stresses in our lives (along with divorce and death). It is NOT the moving - it is the system, which has got so much worse over the past few years.
I moved house to house back in 2003 (aged 62 yrs)and it was bad but quite bearable. When I moved in 2019 it was a total nightmare - we are expected to be lawyers and although paying out large sums to solicitors have to do much of our own research for them.
If you are really interested in this, then do your own research and much of this can be done, easily by reading through the six lots of threads on House Moving Stress - will tell you all you need to know.
