A child is not an asset like a house that gets willed to whoever you choose. In these situations, a court and/or child services will protect the child's rights and well being, if there are no legal guardians. If the child's mother has died, you are still one of the two legal guardians. If your mother becomes the second, that doesn't mean you stop being a legal guardian. If your mother then dies, you are still a legal guardian. The two slots do not have to be filled, one is enough. If you are stripped from your parental rights, your mother adopts, then dies, then the court will decide. If she wills that you again become a legal guardian, that does not undo the stripping of your rights.

One point that Matt mentioned that I found interesting, and certainly gives the service credibility, is that they have lawyers that use their service as well. The lawyer will sell the service to a client for thousands of dollars and then pay RapidAdoption.com to prepare the paperwork for them. There are some that they work with regularly and have an agreement with and some that just purchase the service from their website and give the paperwork to their clients as if they had done it.
