FWIW - every situation is different, but they share a lot of the same problems.
We are a 5th generation ranch with 3 brothers and 2 sisters in my generation. In some respects we are lucky because my brothers each had somewhat different plans than taking over/expanding, and my sisters don't have the skill set.
A couple of things we learned...
1) start talking about things early on. We are already working with our kids (age 8, 6 and 3) to help them understand about the ranching business, scale, future opportunities and expectations around here.
2) have some idea what you want to do/have your business look like before you go visit your accountant. If you just show up and say we want to change generations then there are 100's of options and they can explain them, but can't make a firm recommendation/set of steps. This takes a lot of time, provides no real answers and results in a hefty bill.
3) there are a lot of good and low cost places to obtain expertise. Look at the C-Team Program with the George Morris Center as they do a farm business program that includes succession. (If interested PM me, I have a connection with the program)
4) In Canada there is an option if you are a family farm (not a corp) to go into a partnership for at least 3 years and then roll into a family farm Corp. These have special tax privileges - I am not an accountant but even I understand they can be good.
5) fair is not equal and equal is not fair. If someone is coming back to contribute their sweat, blood and tears that is worth something.
6) life insurance can help - my parents have a life insurance policy. When they pass that money is designated to my non-farming siblings. Farm assets are designated as our inheritance. Everyone gets a share but the business is protected.
7) our farm Gen 1 through 4 have always bought the farm from the generation before. In essence we have purchased the same equity repeatedly. With current land values we have decided here that our course of action is to leverage what has already been paid for and expand. The added cash flow helping to fund "retirement" for mom and dad, rather than the equity from the sale of their land. Reality here is if I paid fair market for the land base (Tanya and I brought some land into the deal too) I would be tits up broke in 6 months ($400K for a quarter to run 15-30 cows).
8) The successor needs responsibilities and skills. Part of the reason we are back is that we have (I hope) the skill set to run a modern ranching business. While not anyone can chase cows, not anyone can negotiate finances, business planning, etc.
9) I work really well with my dad, that helps. It helps if everyone is mostly and honestly ready to undergo big change and shifting of responsibilities. In my mind a succession plan does not mean kids do the work and parents keep the chequebook. (I know some situations like this where the parent and child are in their 80s and 60s respectively).
Every situation is different. I have a friend who is buying the farm from his parents for the same price they paid for it. They have saved and built a retirement fund from the business, and can pass on that opportunity. Not everyone is so fortunate or has the same set of beliefs.
I'd better stop. I could go on and on and on. There are trillions of dollars of assets out their in the farm family community and I would guess that very little of it has a succession plan and a lot of it is held by folks in their later stages of life.
