How to check the license of a font?

Question

Design

Please tell me, I inadvertently used two fonts (as I was sure, free).
One of them is on my mac ( noteworthy light) and the second one I downloaded from some blog, where it was written that it is free for commercial use ( mural script).
On the layout, the fonts are converted to curves, this product will be printed.
But now I began to check and I'm not sure if they are free anymore.
In this connection, 2 questions:
1) How to find out exactly if they are paid?
2) I'm ready to buy them, but what should I do with it? Provide to the customer? Or show the license code in case of claims/questions?
Thanks to everyone who read and thanks in advance for advice/answers.

Answer 1

Where do the doubts come from? Did you check and find something?
And if you can't find it, how do you google it?
How to find out which font is paid and which is not?
+check www.myfonts.com
+check www.parachutefonts.com
+other sites... Google diligently.
In general, the license must be downloaded along with the font. Or it may even be in the font file itself. Look for it or a link to the author's website - and there you can already find information for sure.
And if after all the efforts you can’t find it, then you don’t have to worry about using it.
