Love my wife to bits, she’s a great wife and mother.

Her family however, I just don’t respect them after incident upon incident surrounding her older sister. She is from Ireland and my wife was over for her younger sister’s hen at the weekend and it was a disaster. Another significant incident perpetrated by the older sister.

I need to make sure that upon my death, my children don’t live over there. Three scenarios:

My wife passes away before me then I pass away - I need to legally make sure the kids go to my sister / family here in Scotland.

We both pass away at the same time - same as above.

The tricky one, I pass away with my wife surviving me, can I legally appoint my sister now as a guardian or legally register my objection to this being a scenario in terms of the kids moving to Ireland.

I know folk will want details re why I feel so strongly about this but I don’t want to elaborate. I’d appreciate if folk just trusted my judgement.
