What is the standard of proof needed to establish guardianship?

To establish guardianship, the correct standard of proof required is "clear and convincing evidence." This standard is higher than the preponderance of evidence but lower than beyond a reasonable doubt. Clear and convincing evidence requires that the evidence presented must be substantially more likely to be true than not, establishing a strong belief in the truth of the claims made.

In the context of guardianship, this standard is essential as it ensures that the determination to appoint a guardian over an individual’s affairs is based on a solid foundation of evidence, reflecting the significant impact such a decision has on personal rights and liberties. The rationale behind this standard is to protect the vulnerable individuals for whom guardianship is being sought, ensuring that their autonomy and well-being are respected while also responding to the necessity of oversight in their decision-making capacity.

The other standards mentioned do not align with the legal requirements for establishing guardianship: preponderance of evidence is often used in civil cases but does not carry the same weight as clear and convincing evidence in this context. Beyond a reasonable doubt is the standard used in criminal proceedings, where the stakes involve potential loss of liberty. Substantial evidence refers to an adequate amount of evidence to support a conclusion but is not a recognized legal standard for establishing guardianship
