Where can I send the first half of my Khums if there is no Shia Ahlul Bayt representative in my country? Is it permissible to send the second half to places like Palestine or Lebanon?
Half of the Khums is called Sahm Sadat (The share of needy Sadat). It must be given to needy Sadat who are following Ahlul Bayt (AS) and practicing religious rules. The other half of Khums is called Sahm Imam ( The share of Imam) must be given to the Marje' of Taqleed or his authorised deputies or according to his permission.
You can can send it to the office of Marje' Taqleed in Lebanon or any other authorised deputy who will make it reach to the deserving families in Palestine and Lebanon.
Wassalam.
