Can my 19 year old daughter with no income who qualifies as my dependent be included in her newly wedded husband's married/jointly tax return?

It depends. Generally, her marriage will disqualify you from claiming her as a dependent, but depending on the when she was married and how much support you provided, it is possible.

You could provide additional details and we can analyze it further, but I always recommend my client's check out the IRS's interactive dependent assessment tool which is the authoritative resource for dependent questions. Answer a few questions and it will let you know for sure whether or not you can claim her.

Thank you for your quick response and insight.  Here are some extra details:
-she had no W2 income
-she married in late November
-she moved out a week afterwards
-Turbotax asked us about her details and cleared her as a dependent for our (her parents) tax return

Now her husband is filing his tax return and is running into problems. So, my question was can't he just file married and jointly, but when it comes to her info, her income will be $0 and she will have been claimed as a dependent elsewhere?

You can't claim your daughter as a dependent if she files a joint return with her spouse. 

So either he has to file separately, or you cannot claim her.

You can claim a child, relative, friend, or fiancé (etc.) as a dependent on your 2019 taxes as long as they meet the following requirements:

• They're related to you.
• They aren't claimed as a dependent by someone else.
• They're a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They aren’t filing a joint return with their spouse.
• They're under the age of 19 (or 24 for full-time students).
  • No age limit for permanently and totally disabled children.
• They lived with you for more than half the year (exceptions apply).
• They didn't provide more than half of their own support for the year.
