As for him making these text message demands... must be exhausting for you. Curious to see what comes out of mediation.
In VA a mediator makes suggestions based on typical court rulings of similar cases in the hopes that reasonable parties would just agree to the mediation and save the hassle and expense of court/lawyers.
Just curious, in Canada just how much power over property and custody issues does a Mediator have?
