Hello, and thank you for your question. I am your Expert and I will provide the answer you require.
1. If your Mum and Dad did actually legally adopt your older sister, there would be a formal Adoption Record which you can search for and find in the General Register Office. Here is a link to a webpage which sets out how you can find an Adoption Record for your older sister. Adoption records UK: how to find them - Who Do You Think You Are Magazine. You should search there for the records in relation to your sister. Be aware that if she was legally adopted, then she is entilted to share in the estate of your father. . If she was not legally adopted, then she will not be able to share in your Dad's estate.
2. If you require clarification or if you wish to share additional information, I will be happy to assist further in the resolution of your question.
3. If your sister has your Dad on her Birth Certificate, then you will need a DNA test to establish whether you are full sisters or not, because it will not be possible to ascertain from her Birth Certificate or from an Adoption record whether you were born of the same parents or not. It is possible to apply to court for blood tests to be taken for DNA purposes to establish paternity. So, you would need to make an application to court to have a blood sample taken from your sister to establish paternity and whether your father was in actual fact her father. So, I would advise you to see a solicitor and see about making an application to determine paternity. In the meantime, you should seek out any Adoption Records that may be available.
4. I don't know of any free places you can look for Adoption Records, as most places charge a fee for a search of the Adoption Records. I would suggest you hire someone to do a search for you if you are having no luck doing it yourself.
