There is no time limit for getting a grant.
This thread became a little confused last night. In an attempt to simplify:
D & A may be able to make a claim against whoever administered B's estate if:
- B made a will which left something to them and which was deliberately ignored, or
- B did not make a will but the estate was not distributed correctly in accordance with intestacy rules
However, it will be up to D & A to prove maladministration which will be difficult after all this time.
D & A may have been able to make a claim against B's estate under the Inheritance Act if:
- B made a will which did not leave anything to them, or
- B did not make a will and the rules of intestacy meant they would not receive adequate financial provision
When considering B's estate under the rules of intestacy, remember that, if the family home was owned jointly by B & S as joint tenants, it will have passed directly to S on B's death without forming part of his estate.
If there has not been any grant relating to B's estate it may still be possible to bring an Inheritance Act claim. However, Inheritance Act claims must be started within 6 months of the grant. Even if it is still possible to bring an Inheritance Act claim against B's estate I doubt it would succeed.
Finally, if S has not left anything to D & A they can make an Inheritance Act claim against S's estate. However, I doubt it would succeed. The courts would not be interested in arguments about whether or not S's will was fair. The only question would be whether S had made adequate financial provision. Given that D & A are adults and presumably financially independent it is likely that the courts would decide that they didn't need any provision from S's estate.
So I think the only chance D & A have of getting anything would be if they can show that B's estate has not been administered correctly.
