Pauline Hanson wants to force couples who split up to sort out custody and financial disputes through self-assessment to reduce the burden on family courts.
The One Nation leader's private bill will be debated in the Senate on Monday as Senator Hanson continues her campaign for family law reform.
The legislation requires each partner to get a minimum of 35 per cent of the value of the family home unless one can prove ill health or special circumstances.
Couples would have to self-assess their remaining wealth on an internet portal, with the financially disadvantaged partner assured of getting half the value of their relationship property within 60 days.
The bill's explanatory memorandum says the financially disadvantaged person is female in 94 per cent of cases.
Child custody disputes would also be self-assessed, with the residential parent - usually the woman - forced to articulate reasons for not giving standard contact hours to the father.
People would be able to take their cases to court after the initial resolution, but Senator Hanson expects the incentive to litigate will be reduced, similar to tax self-assessments.
The Senate passed a One Nation motion on Thursday calling for a royal commission or joint select parliamentary committee into Australia's family law system.
Senator Hanson also proposed overtime and earnings from second jobs be quarantined from child support, a change that would overwhelmingly benefit men, who make up about 80 per cent of non-custodial parents.
