I thought adopters shared PR with the LA during placement, and therefore take their lead from the LA re app.ying for a final adoption hearing
This very much depends on the legal status of the child and is quite complex because, unless the LA go to court to have parental rights removed the birth parents retain parental responsibility until the adoption order is granted. So you could have a child where birth parents, LA and adoptive parents all have some degree of parental responsibilities for a child. While we refer to parental rights, they only extend as far as they enable an individual to parent a child so more accurate to talk about parental responsibilities.
If a child is freed for adoption through a court process, the birth parents no longer have parental responsibility (or the rights that go with that), so it’s the LA and foster carer/prospective adopter who has those responsibilities and contact with birth family will usually have ended because they no longer have parental responsibilities. If the child has been freed for adoption it is the adoptive parent who brings the court action to adopt the child and they can do that when they are ready subject to minimum time limits.
If the child has been placed with a plan for permanence but the child hasn’t been freed for adoption, the court process will be to both free the child for adoption and grant the adoption order at the same time. This is the situation where birth parents, LA and prospective adopters all have parental responsibilities to some degree, so birth family contact would continue until the court date, the process is much more open to challenge and appeal, and can mean the adoption order takes longer because the court needs to deal with removing parental responsibility as well as granting the order, so two processes in one. In such a situation the LA and the prospective adopters lawyers will work together - the LA bringing the petition to remove parental responsibilities and the prospective adopters bringing the petition for the adoption order. In reality the LA solicitors will often deal with both and seek a contribution from the adopters in the unlikely event that the LA doesn’t cover the whole bill.
Concurrency planning and foster to adopt have their own quirks to bring to the party in terms of early permanence planning.
In short, law around parental rights is very complex, law around adoption is equally complex - throw birth family, adopters, foster carers into the mix and it’s even more so, with lots of heightened emotions into the bargain. There’s no one single process in moving children through so you’ll get a huge range of experiences all of which might be perfectly reasonable given the specific circumstances of the child and family.
