fence issue - whats the best solution to deal with people who is totally self focused

[Jane Ho]

The property's fence is falling. Tenant request repair. I talked to the neighbors and provided a bid  from licensed contractor at $1200. She said want to go through insurance, then tell me her deductible is $1000 insurance estimated at $2156 so all she can get is 2156/2-1000=$78. Therefore, she wants me to give a letter stating as a neighbor, I refuse to comply with the good neighbor law therefore the insurance will give her $2156-1000 =$1156, then she will have money to pay. I refuse. I do not do things illegal or fishy or fraud. Then quiet for a few weeks, when I follow up, she tells me she quoted around also, the cheapest she find is $2000, and can get it done today! But need me to deliver a cashier check of $1000 today!

My 6th sense says it is like a scam and later find out (she admits) the person she is insisting on using is her own son! Not license, just a vet, but per her own words, 'they canceled his order, he is screwed, he needs work'. and also per her words: I will not pay any third party , since I can pay my son! or '78 dollars I got from my insurance and that's all I will contribute'. 

So there is good neighbor law, there is contractor license law that any project over $500 includes material and labor needs license. I checked, I don't believe his son fits in any exemption. Also, I don't want to be forced to use her son, since I have a much cheaper quote from a licensed contractor! 

I am thinking just paying the $1200 get my own contractor get it done. since if use her son, even I trust it is a fair bid, still will be $1000 out. For $200,  I trust my licensed contractor. My worry is because her son didn't get a penny will she purposely do something on her side to damage the fence and make it fall again next year

sorry I mean the tenants told us they (neighbor) taking down fence without our consent

Update; after clearly stated in writing (text) that we will not hire her son because 1, he is not licensed 2, we feel it is not a fair transaction, the tenant told us they just went ahead starting to taken the fence down. My question: do we owe them anything? Or because the reasons above, we don’t owe anything, if they want to do it, go ahead. 

 Is this the tenant or the neighbour?  If the tenant's son started taking down the fence, you owe him nothing as you didn't authorize it and you should tell him to stop.

 Let them take it down and then you pay to put up the new one.  They may feel this is their way of contributing to the costs.  Just don't pay them any money.
