The ceremony can be brief and still mark a decision that lasts for years.

The size of an occasion has little to do with the weight of what it settles. Ten minutes in a small room, two witnesses, a form signed, and a commitment begins that will shape decades. Length and expense are for the guests. The decision itself needs only to be made clearly and in front of someone.

If you have been delaying something because the marking of it would have to be large, consider doing the small version properly instead. A short ceremony done with attention is not a lesser one. What it starts is the same size either way.
