Its important to distinguish between snooping , spying , tracking and observations and confirming.

1. Key logger. Computer is used by the house. Then this is fine.
If the computer is the 100% owned by the other person or school or work then do not install a keylogger. This the difference between spying and confirming. You are also logging your actions as well.

2. VAR . Carrying a VAR on you that records your interactions with your spouse is legal. Placing a VAR in your car that you use is legal. Leaving one around your home in a room that you use is legal. Everything else is spying. And can cause you legal issues. ( This I would look up with your local laws )

3. Reviewing joint bank accounts , credit cards , phone bills. Legal.

4. P.I. Hiring a registered legal P.I. Legal.

5. Logging into their facebook , emails .... Not legal. If it is caught in the keylogger then you can read the logs. But you cannot take the info and log into their accounts.

If your spouse leaves and you give them a computer as a gift then do not use the keylogger any more. Turn it off. Same with the VAR in a car. You are no longer involved in the day to day activities so this is when it crosses over from tracking and confirming to spying.

And when you go dark.

You go dark.

Dark means no interaction. This includes your tracking and confirming. ( Naturally of course you are going to track joint assets and debts.... but one should not go dark without getting this loose end tied up for full protection )

Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul.
