LS is right with the primary home not being an asset provided you are residing in it (and if he makes you move out, you can apply to have it exempted under hardship grounds until you sort things out)

pps would be around the 640 mark per fn - off the top of my head, i can't recall exact figures

ftb would be (maximum - provided no entitlement to child support at all and greater than 65% care) - ftba 165 per child per fn, ftbb 140 (so approx 470 per fn) - child support may reduce your ftba each fortnight, based on the assessment child support agency make. it will reduce by up to 50c in the dollar for every dollar over the maintenance income free area (about 1800 per year for two kids from memory).

if you are seperating, notify centrelink on the day it happens (or next day) - if you complete all the paperwork for pps within two weeks, you will be paid pps from that date. if you wait, the pps will NOT be backdated to the date you seperate. ftb can be but pps will not be backdated.

hugs hun - i hope it doesn't come to the point of having to go through with this, but if it does/is/has, please contact c'link asap. and make sure you leave yourself a good hour or more for the call. if it's a busy day, it can take a while to get through, and it can take up to half hour or more for the call if you get an inexperienced cso. make sure you have with you the details of all your bank accounts (including balance on that day), assets (car/caravan/boat/rough estimate of value of your household and personal effects, including jewellery), shares, any interests you have in businesses or private companies/trusts. it will make it much faster if you have that at hand
