Technically "yes", but it depends on your context. As Espen930806 notes, "there" is "der". But "there" can also be "det". That's because "there" in English is an overloaded word. It can refer to the existance of something, as in "There is an old woman who lives in a shoe", or it can refer to a location, as in "Put the boxes over there". Without context, I would say that "There is my sock" most often refers to a location. You've been looking for your sock, and just spotted it at the back of the dryer. "Der er min sokk!". But suppose someone says to you "What can we carry these coins in?", and you answer "Well, there is my sock...". That would be "Det er min sokk". My "old woman in the shoe" example would be "Det er en gammel kvinne...". But if I was pointing out someone in a crowd, I would say "Der er en gammel kvinne".
