If I do my own promissary note, and get it signed and witnessed by a ‘notary’ (regarding a loan) is it legally binding and enforceable ?

i am a lawyer but this answer is based on 5 mins on google , yes. and “A promissory note need only be signed and does not require an acknowledgement before a notary public to be valid. ”

Promissory Notes are, in principle, enforceable. But any competent lawyer would be asking:

– where are you? Notaries are practically unknown in England.
– what are you receiving in exchange?
– is there an intention to provide security?

and so on as a minimum.

If it’s a loan worth writing a contract for, it’s a loan worth paying a lawyer for. This is straightforward stuff to someone who knows what they’re doing and you’ll pay not much at all.
