I don’t 100% understand the question here but let me try to answer
Barring exceptions in “special countries” (Cayman islands, BVI, Panama etc) once a board declares a dividend that becomes a legal liability of the company and it goes into books.
So If the company had officially said they “will pay X on date Y to all shareholders on record at date Z” The date this announcement is made is the “declaration date”, X is the dividend, Y is the payment date and Z is ex date.
So what matters is what was declared in the latest company report. The board only committed to pay $1.99 on Q2, they may release guidance on future saying “we will probably profit this much eps will be that much and we will pay that much dividends” but none of this will be binding.
so looking at these a website (investing.com) can put dividend yield on their website.
another website (yahoo) can put Forward yield on their website
There is not a definition of actual dividend, pick your definition and if some website is using that definition you’ll find that value there. If you mean the guaranteed amount there is not guarantee of anything unless you are between “declaration date and payment date” May be forward yield could be closes to what you are looking for but in that case next Domino’s example I’ll give will become tricky and go to 0 yield in between meetings.
Dominos Pizza UK for example at the beginning of pandemic declared that they are not going to pay the dividend (can’t remember the dates, lets say March?) and the next quarter they said things are not as bad as predicted and they reinitiated the dividend with a special ex-date of August (Dominos UK normally pays 2 dividends per annum anyway)
