Is this the correct spelling for Ladie's?

Answer 1

Plural: Ladies

Belonging: Lady's

Your question does not make it clear what you are talking about, but either way, the answer is No.

If you're talking about the plural form of "lady", it's "ladies".

If you're talking about the possessive form of "lady", it's "lady's"

If you're talking about the possessive form of the plural "ladies", it's "ladies'"

The only way that "Ladie's" is correct is if "Ladie" is a proper name (possibly for your dog), in which case "Ladie's" would be the possessive form of your dog's name.

Answer 2

No, the correct spelling is "ladies'". The apostrophe indicates the possessive form of the word "ladies".
