Additional info, but I'm still not certain....
This is right from the IRS's website.
"Constructive receipt. You have constructive receipt of income when an amount is credited to your account or made available to you without restriction. You do not need to have possession of it. If you authorize someone to be your agent and receive income for you, you are treated as having received it when your agent received it."
Using a closing attorney for a real estate sale is essentially authorizing someone to be my agent to receive income for me. That's one of the main reasons people use closing attorneys, to ensure the receipt of funds before the deed is signed over. Multiple people are paid out of the funds, the bank who has a mortgage on the asset being sold, the real estate agent, and the seller, etc. But to me, that reads like I would have constructive receipt of the money. There are no circumstances under which the attorney can choose not to pay me so I basically have a guarantee of receiving that money, and the attorney is acting on my behalf in receiving and disbursing the funds to me.
But I'm not a professional, so I'm not absolutely confident that I'm right.
