I agree with 'then'. I think it is 'doe' not 'doo'.

I think it is 'doe' not 'doo'.

Oops, missed that , you’re right.

Very many thanks to both of you. I wonder why a Father borrowed money from his son.

I wonder why a Father borrowed money from his son.

For the same reason he borrowed money off anyone -- he was in need of extra cash and the son had some to spare

The clause will just ensure that the son gets his £20 back before any other legacies are paid out.
