No problem at all.

The legal rules are different for every country, but technically copyright can last up to 70 years after a copyright legislation has been requested by the owner.

You could always mail yourself a hardcopy of the music notation of your songs, which can prevent any fraud or theft. Which is a great way of safeguarding the rights to your music for free. 

Another recommended option would be to find a trustworthy manager,  if within your budget. Most musicians/bands prefer that, but finding a reliable, reputable manager isn't always easy in the music business.

Just remember that you always have options and talking to other musicians or solo artists on how they promote themselves locally can also be very beneficial.
