We present the results of the investigation of magnetic properties of the
Er

Ti
2
−
x
Sn
x
O
7
series. For small doping values, the ordering temperature decreases linearly with
x
, while the moment configuration remains the same as in the
x
=
0
parent compound. Around
x
=
1.7
doping level, we observe a change in the behavior, where the ordering temperature starts to increase and new magnetic Bragg peaks appear. For the first time, we present evidence of a long-range order (LRO) in
Er
2
Sn
2
O

(
x
=
2.0
) below
T
N
=
130
mK. It is revealed that the moment configuration corresponds to a Palmer-Chalker type with a value of the magnetic moment significantly renormalized compared to
x
=
0
. We discuss our results in the framework of a possible quantum phase transition occurring close to
x
=
1.7
.
