If you apostate shia to another sect can you come back?

[Lion of Shia]

If somebody left shia and joined another sect, like sufi,ect could they comeback?Do they need to renew third shahahdah, Ali waliayun,ect

are they considered apostate and do shias accept them back?

I dunno.  Personally I don't really think of Shiaism as a religion.  They're still within Islam and never left the religion.  I was actually never taught the "third shahada." I've heard it said, but I was never taught that it was required for anything.  

I don't know what the ruling is, but if you are on what you believe to be the right path, and someone deviates from that path, it does not make sense to shun those people and never accept them back to the right path.  Does it?  At least to me it doesn't.  Maybe to others it might.

Salam at first joining another Islamic sect is not apostasy in Shia Islam which any muslim can join to any sect of Islam which returning to shia Islam from other Islamic sect doesn't need renewing anything  which in famous Fatwa of Sheikh Shaltut anyone specially Sunnis can follow Shia (Imami and Zaydi ) jurisprudence although following Sunni jurisprudence is too rare & nearly zero by Shia Muslims due to superiority of Shia jurisprudence over all branches of  Sunni jurisprudence.

Issuance and Significance of the Fatwa

Shaltut's fatwa was issued in response to an inquiry regarding the permissibility of following Imami and Zaydi Shi'a jurisprudence. It was issued by Shaltut, a Hanafi jurist who served as the president of al-Azhar University at the time and was a co-founder of Dar al-Taqrib bayn al-Madhahib al-Islamiyya (House of Proximity among Islamic Denominations). The fatwa was issued on Rabi' al-Awwal 17, 1378/October 17, 1958 which coincided with the birthday of Imam al-Sadiq (a). Representatives from Imami Shiism, Zaydi Shiism, and the four Sunni jurisprudential schools were present during the issuance of the fatwa

Some believe that Shaltut's fatwa was influenced by the efforts of Muhammad Taqi Qummi and Sayyid Husayn Burujirdi during the establishment of Dar al-Taqrib.

Prior to the issuance of this fatwa, Sunni scholars generally did not permit the adoption of Shi'a jurisprudence. It is reported that Shaltut's motivation for issuing this fatwa stemmed from the recognition of the superiority and strength of the arguments in Shi'a jurisprudence, particularly in areas such as inheritance and divorce, when compared to Sunni jurisprudence.
