Think of it like a business with different departments—one person might run the Treasury (Financial/Durable POA), while another manages Health & Safety (Medical POA).
In legal terms, "weight" is determined by the scope of authority defined in the document:
The "Specific" Rule: A POA only has weight in the area it is written for. If you have a Durable Financial POA, it holds 100% of the weight for financial matters but 0% for medical ones.
The "General" POA: You can create a "General Power of Attorney" that covers everything, but most attorneys and bookkeepers prefer separate documents. This is because you might want your daughter (a doctor) to handle medical calls, but your son (an accountant) to handle the books.
The only way a POA is "overridden" is through revocation or court intervention:
Newer Documents: If you sign a new POA today, it typically overrides and cancels any POA you signed three years ago for that same category.
Guardianship: If a court appoints a legal Guardian or Conservator, that court order usually overrides any existing POA documents.
The Principal's Voice: As long as you are "of sound mind," you override everyone. A POA only speaks for you when you can't (or choose not to) speak for yourself.
Independent Bookkeeper's Note: From a record-keeping standpoint, the Durable Power of Attorney is the "heavy lifter" for your estate. Because it is durable, it stays active if you become incapacitated, ensuring the bills get paid and the lights stay on without needing a judge to get involved.
