I had to make a will last year when diagnosed with very serious illness.
I have 2 DS and have been estranged from DS1 for many years - a situation that will not change. I had no desire whatsoever to leave anything to the eldest for very good reasons (e.g. drugs, violence towards me).
I was advised by my solicitor that I should not cut DS1 out of my will as, if I did, he could challenge the will. Solicitor also said that my son would have no difficulty finding a solicitor who would challenge my will on his behalf (due to the amount of the inheritance).
Solicitor said that children who have been excluded from wills are now winning an increasing amount of cases when they challenge the will. Solicitor also said that the excluded son could effectively erode the inheritance through the legal fees that could be payable to fight off the challenge.
So, to ensure that DS2 was able to inherit, I had to put the estate in trust for both sons, with a letter of wishes stating that the primary beneficiary of the trust was DS2 and placing a number of conditions on DS1 before the trust would consider any application from him.
So, I'm surprised to see so many people on here thinking that it's possible to cut someone out of a will because the benefactor's wishes are paramount. That was not the advice I received from a top law firm in my city.
Perhaps I need to seek another legal opinion.
