Legal rights around adoption

[GeekCool]

I was adopted in 1982, I think I was 6 months old when the adoption was finalised, but had been with my parents since six weeks. I have an elder (non biological sister) too.
A couple of years ago, my sister's maternal Grandmother made contact with her through Social Services and a couple of letters where exchanged but that was all.
Through this though, my mum (adoptive) was told that even though in the eyes of the law she is my mum, her and my dad have no legal claim to see my ds if something happened to me. Apparently this is because they are not blood relatives.
Would anyone be able to advise if this is the case or not? I'm hoping not as I can't understand why it would be so, but it worries my mum.
If this is the case, can I rectify it within my will (joint with DH)

Sorry if this is in the wrong place, I'm not sure if it fits here on in the adoption forum really.

I don't beleive that GPs as a whole have a legal right to see their GC as the law stands at the moment. The adoptive part makes no difference. It was in the news recently that there might be plans to change this.

That's right. They are in no weaker position because you are adopted. You might like to make a will and put in that a guardianship clause (lots of posts about that on this forum!).

Ah ok, that makes sense, think I got caught up in the potential unfairness of it all through adoption, but yes thinking rationally it's clearer.
Will definitely look at the posts on Guardianship clauses in wills.

Thank you :)
