Using an overseas return address for Probate letters?

[Steve G.]

Hi BP Members, 

I'm just about to send out letters to my first Probate list. I appreciate some comments on the following questions regarding probates:-

• Is it a requirement (or even a recommendation) to put a return address on the back of the envelope I send out to a Probate list?
• If so, would a New Zealand return address be detrimental to me (ie. no response)?
• Am I more likely to get a response if I have a "local" return address?

Thanks for your input.
