How can i put my grandmothers will in probate ?

I assume you mean "how can I probate my grandmother's will in Florida?" This depends on whether she passed away as a resident of Florida, and whether or not her estate, excluding certain properties, would amount to over $75,000.00. Regardless, you will need to draft documents and file them with the court, as well as attending a hearing. You will also need to publish certain notices to creditors in a local, approved newspaper. For the time you will spend, you might be better off to seek an attorney's help for this.
