Tips/Best ways of arguing with DP....

[TDaDa]

Obviously best not to have argument but if you do what rules/methods do you follow?

I will make the controversial suggestion that texting each other rather than big bust up infront of children could be very effective, allowing civilised exchange and reconciliation. I have tested this, myself with decent results.

What are your views/tips?

Of course, there are some disagreements that should not happen in front of children

Grown-ups know that and react accordingly (wait until they are in bed etc)
