[Avodah] standing for chasan and kallah

[Elazar M. Teitz]

<Can I presume that according to that sefer, since the groom is not yet a chasan until the chupah, there is no reason to skip Tachanun if Mincha is said prior to said chupah?>

     No, because the gathering is one of simcha shel mitzva, even if it has not yet taken place. The day is yom chasunaso v'yom simchas libo. In fact, minhag Yerushalayim is that if a wedding is taking place later in the day -- even after tzeis, IIANM -- the chasan's presence at a minyan results in tachanun not being said.  After all, on the day of a bris we skip tachanun in the presence of father, sandak or mohel, even though the bris may be taking place much later in the day.
