Refusing Sealing (marriages or children to parent) and Baptism by proxy

When reading this [*Wikipedia* article on Sealing](https://en.wikipedia.org/wiki/Sealing_(Mormonism)) there is this paragraph: > The union of a sealed couple is regarded as valid only if both individuals have kept their religious covenants and followed Christ's teachings. **Just as deceased individuals may refuse any temple ordinance (such as a sealing) done by proxy on their behalf**, couples, parents, and children who were sealed to each other in life may refuse to accept a sealing of which they were a part. **No one will be sealed to any one with whom they do not want to be sealed.** I also read this about [Baptism (by proxy) for the dead](https://www.churchofjesuschrist.org/study/manual/gospel-topics/baptisms-for-the-dead) : > Some people have misunderstood that when baptisms for the dead are performed, deceased persons are baptized into the Church against their will. This is not the case. **Each individual has agency, or the right to choose**. The validity of a proxy baptism depends on the deceased person accepting it and choosing to accept and follow the Savior while residing in the spirit world. The names of deceased persons are not added to the membership records of the Church. With the LDS church having practices where my descendants *may* in the future convert into the LDS church, and who then potentially want to baptize me by proxy (after my death) in a temple ordinance, how should I express my desire so that my future descendants will respect my wish *not* to be baptized into the LDS church (or sealed to them) by proxy? Hence the question: **How do individuals who refuse, notify the church so that living members do not attempt to perform temple ordinance on their behalf, after they pass away?** Will noting the wish in their Last Will and Testament be sufficient, or do they need to do something more, such as filling out a form?
