Final answer:
A grantor who is legally competent and has reached the age of majority is essential for a legally valid grant.
Step-by-step explanation:
In the context of law, a grantor refers to a person who transfers property or a right to another person, known as the grantee. When it comes to a grantor's legal competence and age of majority, certain criteria need to be met. A grantor who is legally competent is someone who has the mental capacity to understand the consequences of their actions and make informed decisions.
In most jurisdictions, reaching the age of majority is a requirement for legal competence.
For example, in the United States, the age of majority is usually 18. Therefore, a grantor who is legally competent and has reached the age of majority is considered essential for a legally valid grant.
