$30K gift money. What to do with it?

I would set aside an emergency fund of 3-6 months living expenses and then pay off whatever outstanding debt I had. You probably don't have enough for all of that but get started.  

I would need to know more about your current financial status to give advice. If I received $30,000 after tax, about $10,000 would go into an emergency fund. The next $10,000 would pay off the furnace I had to purchase this year. The rest would significantly update my car.

Bank it, pay down bills with it, send it to me. Lay it on the bed and look at it! You have a lot of choices here!

Depends on what other assets you have and your current income. 

If you didnt have an emergency fund built up...you do now. 

Invest in a property

Retirement savings

Invest, $1000 a month for the next 30 months. S&P 500 index fund.  Then add more after that.  Don't consider touching it for 30-40 years.

First, split it evenly, so there is no fighting later. Then save some, and then go have some fun with the rest of it!

Well, for one ting, asking in Personal Finance would make better sense.

Right now, I'd say staying out of stocks would be the right choice. Insured investments, like a good mutual fund, would be best.

In the US, you should be OK for taxes, gifts of $15K a person per year are tax free.
