A notary is different from a JP, a notary's seal is recognised internationally, which is why notarisation costs more than a free JP certification. Use a notary only when documents are going overseas.
A notary public certifies documents for overseas use, their seal is internationally recognised, unlike a free JP certification which is only for domestic use. Check whether you also need an apostille or embassy legalisation for the destination country.
💰 Ways to save
- For domestic certified copies, a free Justice of the Peace is enough, use a notary only for overseas documents.
- Bundle several documents in one appointment, it is cheaper than separate visits.
- Confirm whether the destination country needs an apostille or embassy legalisation before you start.
