You've already got the game plan. The Good Neighbor Fence Act of 2013 (Civil Code section 841) states that a fence on the border of adjoining landowners benefits both neighbors and each must share in the costs of the repairing or maintaining the fence. So at the very least, your neighbor would be responsible for paying for half of the costs to repair your common fence.
In order to require the neighbor to pay for half of the repairs, maintenance or replacement of the mutual border fence, you’ll have to give 30-days written notice of the work to be done to your neighbor. Then you can begin the work and if your neighbor doesn’t pay for half, then you can sue your neighbor for half of the costs.
