This money laundering crap is a pain in the arse.
My wife is waiting for her share of her parents assets, and my son (an accountant) has been helpibgbjer set up various investments and accounts.
The money will come from a traceable UK bank account, with the solicitor into a joint account, where I am tasked with distributing it to her new accounts. On attempting to open a "Marcus" account, there is a question about where the money comes from.
They ticked inheritance.
It now requires death certificate, copy of will, and a letter from.the solicitor.
We don't have these and asking the Executor to obtain them is apparently too much stress for him. The solicitor is an arse anyway. I told him, not to deal with the firm he used, because I've had dealings with them and they were uselessly ineffective.
Going back and attempting to tick a different box is apparently not possible.
