An important question I ask of all clients is whether they have a secure e-mail address and a "safe place" to receive mail from my office. When spouses are in the beginning phases of the divorce process, accidentally alerting the other spouse to divorce plans can have a negative impact ranging from tipping one’s hand early too early or up to and including domestic violence in extreme cases.
If you plan to correspond with your attorney via e-mail, make absolutely sure that your spouse cannot access your e-mail account. You might consider changing your password or opening a new e-mail account.
In terms of "snail mail," you might consider renting a PO Box through a United States Post Office location or a private company such as the UPS Store, or Mailboxes, etc. This is an inexpensive way to make sure your confidential communications with your attorney are not compromised.
Update: William L. Wilson of the Indiana Family Law Blog published the following article about this post:
When I ran across this article from the Georgia Family Law Blog, I knew I had to post it today.
In a nutshell, the author recommends making sure that clients secure their email (change the password or set up a new account) and consider obtaining a post office box for receiving mail.
I would add a couple of notes to this discussion. One, beware of using your cell phone. A spouse who is abusive or controlling may review the cell phone records and learn that you are communicating with an attorney.
Second, when it comes to password-protecting your email account, remember to use good passwords: avoid obvious choices (names, favorite words, etc.) because those are easily guessed. The best passwords are randomly generated, but those are hard to remember. A safe alternative is to use two random words separated by a number, such as grip7sink.
For the ultimate in security, consider using encryption tools like PGP or GnuPG. They are not for the faint of heart, but they get the job done. Unfortunately, too few legal professionals use encryption software to communicate with their clients, probably because so few clients are set up to use it.
